I'm working on a non-profit's website and social media presence. They are currently using an outdated website built on WordPress and we're working on a limited budget to improve it. I have suggested we go with a more up-to-date WordPress theme as this would keep costs as low as possible.
The question that remains is how easy/cost-effective (in terms of labor) is it to take a large amount of content (mostly text) and transfer it to a new WordPress theme? Would this mean the website would be down for an extended period of time while we implement existing content? or would we be able to backup the content, apply a new theme, and upload the content from the backup? Is this a simple process or an extended process? I'm going to estimate there are about 150-200 pages worth of content. At a rate of $30/hour for labor, how much would this end up costing us?
